Question

If x = 30 degree ,verify that tan2x = 2tanx / 1-tan²x

Answer 1

Step-by-step explanation:

Hey mate here ur solution ..

X = 30° (given)

Putting value of x ..

tan 2 × 30° = 2 tan 30° / 1- tan²30°

tan 60° = 2 × 1/√3 ÷ 1 - (1/√3)²

√3 = 2/√3 × 3/2

√3 × √3 = 3

3 = 3

So , LHS = RHS

Hope it helps u :-)
